FIELD: chemistry.
SUBSTANCE: invention relates to chemical industry and may be used for producing graphite foil, adsorbents and heat resistant substrates for catalysts. Initial powder graphite is processed at room temperature in continuous mixing of minced cobalt oxide Co3O4 in concentrated sulphuric acid and cured for 2 to 24 hours. Produced intercalated graphite compound is filtered out from solution, subjected to hydrolysis and rinsed by distilled water. Now, it is dried at 60 °C - 80 °C.
EFFECT: composite material with variable content of Co3O4 in oxidised graphite and foam graphite.
